Definitions

  • the present invention provides methods to promote the differentiation of pluripotent stem cells into insulin producing cells.
  • the present invention provides a method to produce a population of cells expressing markers characteristic of the pancreatic endoderm lineage, wherein greater than 50% of the cells in the population co-express PDX1 and NKX6.1.
  • ⁇ cells insulin-producing cells
  • ⁇ cells appropriate for engraftment.
  • One approach is the generation of functional ⁇ cells from pluripotent stem cells, such as, for example, embryonic stem cells.
  • a pluripotent cell gives rise to a group of cells comprising three germ layers (ectoderm, mesoderm, and endoderm) in a process known as gastrulation.
  • Tissues such as, for example, thyroid, thymus, pancreas, gut, and liver, will develop from the endoderm, via an intermediate stage.
  • the intermediate stage in this process is the formation of definitive endoderm.
  • Definitive endoderm cells express a number of markers, such as, HNF3 beta, GATA4, MIXL1, CXCR4 and SOX17.
  • pancreas arises from the differentiation of definitive endoderm into pancreatic endoderm.
  • Cells of the pancreatic endoderm express the pancreatic-duodenal homeobox gene, PDX1.
  • PDX1 expression marks a critical step in pancreatic organogenesis.
  • the mature pancreas contains, among other cell types, exocrine tissue and endocrine tissue. Exocrine and endocrine tissues arise from the differentiation of pancreatic endoderm.
  • islet cells bearing the features of islet cells have reportedly been derived from embryonic cells of the mouse.
  • Lumelsky et al. Science 292:1389, 2001
  • Soria et al. (Diabetes 49:157, 2000 ) report that insulin-secreting cells derived from mouse embryonic stem cells normalize glycemia in streptozotocin-induced diabetic mice.
  • Hori et al. (PNAS 99: 16105, 2002 ) disclose that treatment of mouse embryonic stem cells with inhibitors of phosphoinositide 3-kinase (LY294002) produced cells that resembled ⁇ cells.
  • Blyszczuk et al. reports the generation of insulin-producing cells from mouse embryonic stem cells constitutively expressing Pax4.
  • retinoic acid can regulate the commitment of embryonic stem cells to form PDX1 positive pancreatic endoderm. Retinoic acid is most effective at inducing Pdx1 expression when added to cultures at day 4 of embryonic stem cell differentiation during a period corresponding to the end of gastrulation in the embryo ( Diabetes 54:301, 2005 ).
  • Miyazaki et al. reports a mouse embryonic stem cell line over-expressing Pdx1. Their results show that exogenous Pdx1 expression clearly enhanced the expression of insulin, somatostatin, glucokinase, neurogenin3, p48, Pax6, and Hnf6 genes in the resulting differentiated cells ( Diabetes 53: 1030, 2004 ).
  • mouse model of embryonic stem cell development may not exactly mimic the developmental program in higher mammals, such as, for example, humans.
  • D'Amour et al. describes the production of enriched cultures of human embryonic stem cell-derived definitive endoderm in the presence of a high concentration of activin and low serum ( Nature Biotechnology 2005 ). Transplanting these cells under the kidney capsule of mice resulted in differentiation into more mature cells with characteristics of some endodermal organs. Human embryonic stem cell-derived definitive endoderm cells can be further differentiated into PDX1 positive cells after addition of FGF-10 ( US 2005/0266554A1 ).
  • D'Amour et al. states: "We have developed a differentiation process that converts human embryonic stem (hES) cells to endocrine cells capable of synthesizing the pancreatic hormones insulin, glucagon, somatostatin, pancreatic polypeptide and ghrelin. This process mimics in vivo pancreatic organogenesis by directing cells through stages resembling definitive endoderm, gut-tube endoderm, pancreatic endoderm and endocrine precursor en route to cells that express endocrine hormones”.
  • hES human embryonic stem
  • Fisk et al. reports a system for producing pancreatic islet cells from human embryonic stem cells ( US2006/0040387A1 ).
  • the differentiation pathway was divided into three stages. Human embryonic stem cells were first differentiated to endoderm using a combination of sodium butyrate and activin A. The cells were then cultured with TGF- ⁇ antagonists such as Noggin in combination with EGF or betacellulin to generate PDX1 positive cells. The terminal differentiation was induced by nicotinamide.
  • Benvenistry et al. states: “We conclude that over-expression of PDX1 enhanced expression of pancreatic enriched genes, induction of insulin expression may require additional signals that are only present in vivo " ( Benvenistry et al, Stem Cells 2006; 24:1923-1930 ).
  • Grapin-Botton et al. states: "Early activation of Ngn3 almost exclusively induced glucagon+ cells while depleting the pool of pancreas progenitors. As from El 1.5, PDX-1 progenitors became competent to differentiate into insulin [positive] and PP [positive] cells" ( Johansson KA et al, Developmental Cell 12, 457-465, March 2007 ).
  • Chen et al states "(-) -indolactam V [(ILV)] activates protein kinase C signaling and directs the pancreatic specification of hESCs that have already been committed to the endoderm lineage...ILV and retinoic acid function through a related mechanism...ILV shows a stronger induction of PDX-1 expressing cells (percentage of cells expressing PDX-1) than does retinoic acid.” ( Nature Chemical Biology 5, 195-196 (April 2009) doi:10.1038/nchembio0409-195 ).
  • Lyttle et al states: "NKX6-1 co-localised only with insulin cells, indicating that NKX6-1 is exclusively involved in human beta cell development.” (Diabetologia 2008 Jul: 51(7):1169-80, 2008 ).
  • the present invention takes an alternative approach to improve the efficiency of differentiating human embryonic stem cells toward insulin expressing cells, by generating a population of cells expressing markers characteristic of the pancreatic endoderm lineage, wherein greater than 50% of the cells in the population co-express PDX-1 and NKX6.1.
  • the present invention provides a population of cells expressing markers characteristic of the pancreatic endoderm lineage, wherein greater than 50% of the cells in the population co-express PDX1 and NKX6.1.
  • the present invention provides a method to differentiate a population of pluripotent stem cells into a population of cells expressing markers characteristic of the pancreatic endoderm lineage, comprising the steps of:
  • greater than 50% of the cells in the population of cells expressing markers characteristic of the pancreatic endoderm lineage produced by the methods of the present invention co-express PDX-1 and NKX6.1.
  • Figures 1A and 1B show the expression of PDX1, NKX6.1 and ISL-1 at stage 4 day 4 of the differentiation protocol outlined in Example 1.
  • Figure 1A shows the expression of PDX1 and NKX6.1.
  • Figure 1B shows the expression of NKX6.1 and ISL-1.
  • Figures 2A and 2B show the effect of PKC activator treatment on the percentage of cells expressing PDX1, NKX6.1 and CDX2, analyzed via the IN Cell Analyzer 1000 ( Figure 2A ), and comparison of various PKC activator and their effects on percentage of PDX1 and NKX6.1 expressing cells , via the IN Cell Analyzer ( Figure 2B ).
  • Figures 3A, 3B and 3C show circulating C-peptide in SCID-beige mice that received the cells of the present invention under the kidney capsule ( Figure 3A ), in a Theracyte device that was implanted subcutaneously ( Figure 3B ). C-peptide levels were detected at the times indicated.
  • Figure 3C shows a comparison of the C-peptide levels observed between the group receiving the cells under the kidney capsule and the group receiving the cells in the Theracyte device subcutaneously, at 12 weeks post-transplantation.
  • Figures 4A, 4B, 4C and 4D show the effect of PKC activator treatment on the expression of PDX1, NKX6.1, NGN3 and PTF1 alpha expression in cells treated according to the methods described in Example 3.
  • Figures 5A, 5B, 5C and 5D show the effect of FGF7 on the expression of NKX6.1, PDX1, PTF1 alpha and CDX2 in the cells treated according to the methods described in Example 4.
  • Stem cells are undifferentiated cells defined by their ability at the single cell level to both self-renew and differentiate to produce progeny cells, including self-renewing progenitors, non-renewing progenitors, and terminally differentiated cells. Stem cells are also characterized by their ability to differentiate in vitro into functional cells of various cell lineages from multiple germ layers (endoderm, mesoderm and ectoderm), as well as to give rise to tissues of multiple germ layers following transplantation and to contribute substantially to most, if not all, tissues following injection into blastocysts.
  • Stem cells are classified by their developmental potential as: (1) totipotent, meaning able to give rise to all embryonic and extraembryonic cell types; (2) pluripotent, meaning able to give rise to all embryonic cell types; (3) multipotent, meaning able to give rise to a subset of cell lineages but all within a particular tissue, organ, or physiological system (for example, hematopoietic stem cells (HSC) can produce progeny that include HSC (self- renewal), blood cell restricted oligopotent progenitors, and all cell types and elements (e.g., platelets) that are normal components of the blood); (4) oligopotent, meaning able to give rise to a more restricted subset of cell lineages than multipotent stem cells; and (5) unipotent, meaning able to give rise to a single cell lineage (e.g., spermatogenic stem cells).
  • HSC hematopoietic stem cells
  • Differentiation is the process by which an unspecialized ("uncommitted") or less specialized cell acquires the features of a specialized cell such as, for example, a nerve cell or a muscle cell.
  • a differentiated or differentiation-induced cell is one that has taken on a more specialized ("committed") position within the lineage of a cell.
  • the term "committed”, when applied to the process of differentiation, refers to a cell that has proceeded in the differentiation pathway to a point where, under normal circumstances, it will continue to differentiate into a specific cell type or subset of cell types, and cannot, under normal circumstances, differentiate into a different cell type or revert to a less differentiated cell type.
  • De-differentiation refers to the process by which a cell reverts to a less specialized (or committed) position within the lineage of a cell.
  • the lineage of a cell defines the heredity of the cell, i.e., which cells it came from and what cells it can give rise to.
  • the lineage of a cell places the cell within a hereditary scheme of development and differentiation.
  • a lineage-specific marker refers to a characteristic specifically associated with the phenotype of cells of a lineage of interest and can be used to assess the differentiation of an uncommitted cell to the lineage of interest.
  • Cells expressing markers characteristic of the definitive endoderm lineage refers to cells expressing at least one of the following markers: SOX17, GATA4, HNF3 beta, GSC, CER1, Nodal, FGF8, Brachyury, Mix-like homeobox protein, FGF4 CD48, eomesodermin (EOMES), DKK4, FGF17, GATA6, CXCR4, C-Kit, CD99, or OTX2.
  • Cells expressing markers characteristic of the definitive endoderm lineage include primitive streak precursor cells, primitive streak cells, mesendoderm cells and definitive endoderm cells.
  • Cells expressing markers characteristic of the pancreatic endoderm lineage refers to cells expressing at least one of the following markers: PDX1, NKX6.1, HNF1 beta, PTF1 alpha, HNF6, HNF4 alpha, SOX9, HB9 or PROX1.
  • Cells expressing markers characteristic of the pancreatic endoderm lineage include pancreatic endoderm cells, primitive gut tube cells, and posterior foregut cells.
  • Definitive endoderm refers to cells which bear the characteristics of cells arising from the epiblast during gastrulation and which form the gastrointestinal tract and its derivatives. Definitive endoderm cells express the following markers: HNF3 beta, GATA4, SOX17, Cerberus, OTX2, goosecoid, C-Kit, CD99, and MIXL1.
  • Markers are nucleic acid or polypeptide molecules that are differentially expressed in a cell of interest.
  • differential expression means an increased level for a positive marker and a decreased level for a negative marker.
  • the detectable level of the marker nucleic acid or polypeptide is sufficiently higher or lower in the cells of interest compared to other cells, such that the cell of interest can be identified and distinguished from other cells using any of a variety of methods known in the art.
  • Pancreatic endocrine cell or “Pancreatic hormone expressing cell”, or “Cells expressing markers characteristic of the pancreatic endocrine lineage” as used herein, refers to a cell capable of expressing at least one of the following hormones: insulin, glucagon, somatostatin, and pancreatic polypeptide.
  • Pluripotent stem cells may express one or more of the stage-specific embryonic antigens (SSEA) 3 and 4, and markers detectable using antibodies designated Tra-1-60 and Tra-1-81 ( Thomson et al., Science 282:1145, 1998 ). Differentiation of pluripotent stem cells in vitro results in the loss of SSEA-4, Tra 1-60, and Tra 1-81 expression (if present) and increased expression of SSEA-1. Undifferentiated pluripotent stem cells typically have alkaline phosphatase activity, which can be detected by fixing the cells with 4% paraformaldehyde, and then developing with Vector Red as a substrate, as described by the manufacturer (Vector Laboratories, Burlingame Calif.). Undifferentiated pluripotent stem cells also typically express OCT4 and TERT, as detected by RT-PCR.
